基于广义五阶Henon映射以及五阶细胞神经网络系统所产生的超混沌现象,设计了图像加密方案。首先利用五阶Henon映射产生超混沌序列X,将其作为细胞神经网络系统的初始条件,再产生另一超混沌序列Y,随机序列Y和原始图像经过变换生成密文图像。在此基础上进行了模拟仿真实验,并对图像密文熵、相关性和直方图以及密钥空间和敏感性等统计特性进行分析,结果表明:该算法图像加密抗攻击性强,安全性好,适于在网络中传播。
基于廣義五階Henon映射以及五階細胞神經網絡繫統所產生的超混沌現象,設計瞭圖像加密方案。首先利用五階Henon映射產生超混沌序列X,將其作為細胞神經網絡繫統的初始條件,再產生另一超混沌序列Y,隨機序列Y和原始圖像經過變換生成密文圖像。在此基礎上進行瞭模擬倣真實驗,併對圖像密文熵、相關性和直方圖以及密鑰空間和敏感性等統計特性進行分析,結果錶明:該算法圖像加密抗攻擊性彊,安全性好,適于在網絡中傳播。

Image encryption scheme was designed based on the hyper chaos of generalized five order Henon map -ping and five order Cellular Neural Network system .Firstly, the chaotic sequence X , which was regarded as the initial conditions of Cellular Neural Network system , was generated by the five order generalized Henon mapping .Then anoth-er chaotic sequence Y was produced by CNN system .Then, the cipher image was generated by the transformation of random sequence Y and the original image .Finally, the simulation experiments and results showed that the algorithm of image encryption had strong attack resistance , good safety , and was suitable to spread in the network through analyzing the statistical characteristics of timage information entropy , correlation and histogram as well as the key space and the sensitivity.
